To all whom t may concern:

Be it knowntlrat LALn'RO-Y B. ARRIS, a citizen of the United States', and a resident of Clay county, Iowa, have invented certain new and useful Improvements in Resilient Vheels, of which the following is a speci-tication. p

My invention is an improvement in resilient wheels, and has for its object toV provide a tire for taking the piace of the pneumatic tire, wherein resilient mechanism is provided` Within the usual shoe or casing,po`s sessing practicaliy all the advantages ofthe pneuniatic tire, but which will notbe iessened in resiliency by puncture or blow out.

Figure 1 is a side view of a wheel pro vided with the improved tire, with parts in section,

Fig. 2 is a perspective view of a portion of the riin,

Fig. 3 is a sectionon the line SH3 oi' Fig. 1 looking inl the direction of the arrows adjacent to the line, Y

Fig. el is a perspective view of one of the shoes,

Fig. 5 is asimilar view of a portion of the inner rings showing the joint between the sections,

Fig. 6 is a perspective view of one ofthe holding pins, and

Fig. 7 is a perspective view of the de- Y mountable rini.

The present embodiment of the invention is shown in connection with a. wheel 1 having the usual elly 2, and provided with a quick demonntable rini. This riin rests upon a ring 3 fitting the outer face of the telly and haring at one edge an oblique flange At the opposite side edge a retaining` ring 5 lits against the side of the telly and is retained in place by bolts '6 and nuts 7, the said retaining ringhaving an inwardly eX- tending rib 8 engaging over the outer face of the ring 3 and the inner face of the rib is inclined as shown, at the saine angle as the oblique flange 4l. The delnountable rim 9 has the usual oblique Hanges at its side edges, and the said rini is a split rim, the ends of the riin at the split being connected by a cross plate 10 which is connected tothe riin by screws 11. The demountable rnn 9 1s provided on its under side with circumferentially extending ribs 12 which are adapted to engage the inner faces of the flange 4 and the rib 8, to hold the dernountable rim in.

proper position on the wheel, and at the plate ltlthese ribs are cut away as shownin Fig. 2, in order that the inner face of the plate may be fiush with the inner face of the ribs.

The shoe or casing 13 is of the clencher type and the side edges are held in place on thel deinountable riin by retaining rings 14, the said rings being shaped to fit the retaining ribs of the shoe or casing vand to engage within theI fianges 10 of the dcmountable riin in the usual manner. 1Witliin the casing and at the tread thereof, is arranged a strip 15 of leather, the said strip extending entirely around the tire, and it will be noticed `from an inspection of Fig. 8, that the side edges olf the strip are beveled.

A series of shoesl is arranged within the shoe or casing 13, each of the said shoes comprising a body 16 which is curved trans verselyv to fit the inner face of the strip 15 of leather, and an inwardly extending lug 17 at each end of the body. "These lugs have series of slots V18, the said slots being space'd apart from each other as shown, and an opening 19' is `provided extending transversely-of the slots for receiving a rivet or the like, for a purpose to be described.`

These slices 16 are arranged with their ends spaced apart, as shown inore particularly in Fig. 1, and they are connected by the links Q0, the said links engaging the slots 1S at their ends, and a rivet is passed through the opening 19 and through registering openings in the links to pivotally connect the shoes at their adjacentends. In the present instance each pair oi adjacent shoes is con neeteld' by three links, the said links being parallel and spaced apart from each other, as shown.

Each shoe 16 has on its inner face, and adjacent the inner sides of the lug 17, a pair of retaining abutinents 21, and a pair oi coil springs 22 is arranged between each shoe and the deniountable rim, the outer ends of the springs engaging the abutments 21, which properly space the said outer ends andhold them in shape. The inner ends oi3 the springs engage similar abutments 21a on the demountablc rim. A pair of sectional rings is arranged on the demountable rini, the members of the pair being at opposite sides of the shoe or casing 13, and each of the said rings is composed of four sections 22, and the ends of the sections. abut as shown in Fig. 5.,

The corresponding sections of the rings are connected by the pins 23, shown in Fig. 6, each pin having its ends reduced Vand oppositely threaded, and the said ends are engaged with threaded openings in the ring sections. Shoulders are formed at the inner j ends of the reduced and threaded portions, and these shoulders abutting the inner faces of the sections, limit their movement toward each other. rllhey are further limited by the angle plates 2st, which are arranged at the ends of the sections, between corresponding sections of the pair, each angle plate having one portion radial and the other circumferential to the wheel, and the radial portions of the plates abut, as shown. Spacing plates 25 of T-shape are arranged between the sec tions intermediate the ends thereof, and between the adjacent ends of the shoes 16. The adjacent ends of the sections are connected by the plates 26, the said plates being secured to the abutting ends of the sections in any usual or desired manner, and extend ing upon each side of the joint for a short distance.

The improved tire is assembled on the demountable rim and then placed on the wheel. The parts are assembled with the demountable rim in the position of Fig. 7, that is with the ends lapping. The sections of the holding rings 22 are assembled, after which the said sections may be placed within the casing'. The shoes are first placed, and afterward the springs. The holding ring sections are then placed, and the casing is connected with the rim, the rim being at this time in the position of l? i g. 7. Alter the parts have been so placed, the rim is spread until the ends abut, aEter which the plate 10 is placed, and the assembled tire may be placed upon the wheel. The springs are held in place during' the placing of the rim by the abutments 21a.

Mechanism is provided Yfor holding the retaining rings 14 in place until the rim 9 is expanded. The said mechanism, as shown in Fig. 3, consists of a series of clamps, each comprising a substantially U-shaped cyl-.imp consisting oit a body 27, and arms 2S and 29 extending laterally from the body. The arm 28 has an inwardly extending lng 30 which engages one of the rings 14 exter- Copies of this patent may be obtained for five eentspeach, by addressing nally, and a screw 31 is threaded through the other arm to engage the other ring. As soon as the rim is expanded it will hold the rings 14 in place.

I claim:

1. A wheel of the character specified having a rim, a casing, and means for connect ing the casing to the rim, cushioning mechanism within the casing and comprising pairs of coil springs arranged radially of the wheel, a shoe for each pair of springs, each shoe being curved to lit the inner face of the casing and having inwardly extending lugs at its ends, a series of links connecting the lugs ot each adjacent pair of shoes, said lugs having openings extending cir cumferentially of the wheel for receiving the ends of the links, and a pair of retain ing rings within the casing, said rings being at opposite sides of the springs and each ring being sectional, and the corresponding sections of the rings being connected together in spaced relation.

2. A wheel of the character specified having a rim, a casing, and means for connecting the casing to the rim, cushioning mechanism within the casing and comprising pairs of coil springs arranged radially of the wheel, a shoe foreach pair of springs, each shoe being curved to lit the innerl face ofthe casing and having inwardly extending lugs at its ends, links connecting the lugs of adjacent shoes and pivoted to the lugs, and retaining rings at opposite sides of the springs, said rings being connected together in spaced relation and being sectional, for the purpose specified.

3. ln a wheel o'r` the character specified, a split rim and a casing, and means for connecting the casing to the rim, pairs of coil springs arranged radially within the casing,`

a shoe for each pair of springs, each shoe being curved to fit the inner tace of the tire easing and havinginwardly extending lugs at its ends, links pivotally connecting the lugs of adjacent shoes, and retaining rings at opposite sides of the springs, said rings being connected together in spacedV relation.
